Y SIIUTT'LE.

To kall fw/'mmt may concer/n.'

Be it known that I, JAMES SHAW, a citi- .zen of the United States, .and a resident of Paterso'n, in thecounty of Passaicand'State of New Jersey, have invented,v a new and Improvedl Shuttle, of which the following is a full, clear, and exact description.

This invention relates to a shuttle. In most shuttles now in usethere isa recess at one` end in which a tensioning device is disposed.` Inthis recess a plurality of Ypins are located which are usually mounted therein by boring holes throughl the body of the shuttle and fastening'k the pins therein. These pins are generally not rotatable and in due time become worn by the thread which is constantly rubbing thereagainst. When they are worn or broken by the thread they have to be removed, and in removing them the holes in which they are mounted have to be slightly enlarged. When new pins are put in these holes they have to be sealed therein and oftentimes the sealing material gets loose and the pins drop out, causing the imperfect operation of the shuttle and also sometimes considerable damage to the warp thread. Furthermore, to repair a warp thus damaged requires considerable time and expense to replace the great number of threads broken out.

It is the main object of my invention to provide a means within the recess at one end of the shuttle for mounting the pins that are used in conjunction with the rtensioning device, this mounting being in the form of a box which can be very readily inserted into the recess and removed therefrom.

Another object concerns the provision of simple and efficient means whereby the pins are loosely mounted in the box and can rotate, so that the wear on them due to the rubbing of the thread is considerably reduced. A further object concerns the provision of simple and eiiicient means whereby the pin box is very easily insertedV in the recess and is held therein by a single screw, this screw also serving as a pivot pin for the tensioning device as well.

The invention is illustrated in the drawings, of which- Figure 1 is a partial elevation of one end of the shuttle;

taken on` the line Fig. 4 `isa section of Fig. 3f; Y

Fig. 5v is a perspective view of the pin box; and

Fig. 6 is a section taken onthe line 6-6 of Fig.,5.

The form of the .drawingszis a preferredlform, although` it isunderstood that modifications in the construction and arrangement ofthe parts and invention shown in the yin the character yof the materials used may`l be adopted kwithout departing from the spiritfof the:invention as set forth in the appended claims.

The preferredI form of the invention is applicable vto ashuttle 1 having a recess'ff 2in` one .end thereof. Through this recess a filler thread 3 is adapted to extend. This thread generally comes in contact with a plurality of stationary pins, such as 4, and also in contact with a plurality of eyes 5 mounted on an arm 6 pivoted on a screw 7, this arm and the eyes forming a tensioning device for the filler thread. One end 8 of the arml is connected to a resilient member 9 which is fastened at a fixed point 10, so that the resilient member will hold the arm 6 in a definite normal position. It is the mounting of the stationary pins 4 that has hitherto caused trouble in the operation of shuttles, and the expenditure of time and labor to replace them when broken or when they have become lost. However, I provide a box formed of two parallel plates 11 and 12 kof metal, preferably connected to an end wall 13 which has a tit or projection 14 thereon. These plates are provided with suitable aligning apertures in which the pins 4 are disposed, the apertures being slightly larger than the diameter of the pin so that the pins can rotate therein and can be readily inserted. This box is covered by a similarly shaped casing 15 of very thin metal, merely for the purpose of preventing the pins from -dropping out of the box.

The box and this thin sheet of metal are provided with aligning apertures 16 through which the screw 7, extends, this screw being disposed at its opposite ends in the bodyv its notch and the apertures 16 are aligned with the holes in the shuttle body so that the screw 7 may be introduced intoplaoe, this screw also aotingzas a pivot pin for the tensioning device 6. i

In this manner, therefore, if any of the pins should become Worn, it is merely necessary to remove the screw 7 -Whereupon Jthe entire box can be slipped out of the recess, then by merely removing the thin sheet or casing 16 the pins will drop right out of ytheboxV and can be Ireplaced readily by new pins. i i
